Thorne's Carnityl® (acetyl-L-carnitine) supports the health of the nerves in the upper and lower limbs and enhances the production of the neurotransmitter acetylcholine, which supports brain function.* Acetyl-L-carnitine also helps minimize the discomfort due to alterations in nerve function.* Acetyl-L-carnitine is better absorbed and crosses the blood-brain barrier more rapidly than L-carnitine.*Studies have demonstrated its effectiveness in supporting cognitive health and maintaining a positive mood in the elderly, possibly by partially inhibiting the activity of the hypothalamic-pituitary-adrenal axis and lowering elevated cortisol levels, which become elevated during stress.* In addition to acetyl-L-carnitine's support of brain and nerve health, it also supports healthy sperm count and motility.*
